||Originally named Talcott, Walloon Lake was renamed by local butcher,
J.R. Haas, after he had seen the name on an old railroad map. An investigation by the railroad found before a group of Walloons, from Belgium, had settled the north end of what was then Bear Lake. No trace of this family has ever been found.
Walloon Lake existed in the pre-glacial times as a river valley, which was re-shaped and deepened by glacial activity, it is the 26th largest lake in Michigan, with a lake surface area of 7.3 square miles and a shoreline of 30 miles. It is 9.2 miles at its longest point, from Mud Lake at the tip of the West Arm to the Foot, is mean and maximum depths of 28.9 feet and 100 feet respectively, and is about 100 feet above the elevation of Little Traverse Bay (about 1 mile any).
Walloon Lake is famous as the earthly paradise of Ernest Hemingway as his family spent its summers there when he was growing up.
